Aerial package delivery system

ABSTRACT

Systems and methods for delivering packages via aerial vehicles are disclosed. The system can comprise a label that includes a parachute to enable the packages to be dropped from the aerial vehicle, yet land at the package&#39;s destination without damage. The system can include a self-adhesive backing, a plurality of parachute cords, a parachute, and a breakaway cover. The parachute cords can include a shock absorber to reduce the shock on the package of the parachute opening. The parachute and/or the breakaway cover can include graphics to provide address, velocity, or spin information for the package. The parachute cords can include a harness to separate the cords and reduce tangling of the cords and spinning of the parachute canopy with respect to the package.

CROSS REFERENCE TO RELATED APPLICATIONS AND PRIORITY CLAIM

This Application is a continuation of, and claims priority under 35U.S.C. § 120 to, U.S. patent application Ser. No. 14/836,112, filed Aug.26, 2015, of the same title, the contents of which are incorporatedherein as if fully set forth below.

BACKGROUND

Unmanned aerial vehicles (UAVs) comprise a variety of vehicles, fromconventional fixed wing airplanes, to helicopters, to ornithopters(i.e., machines that fly like birds), and are used in a variety ofroles. They can be remotely piloted by a pilot on the ground or can beautonomous or semi-autonomous vehicles that fly missions usingpreprogrammed coordinates, global positioning system (GPS) navigation,etc. UAVs also include remote control helicopters and airplanes used byhobbyists.

UAVs can be equipped with cameras to provide imagery during flight,which may be used for navigational or other purposes (e.g., to identifya house address). UAVs can also be equipped with sensors to providelocal weather and atmospheric conditions, radiation levels, and otherconditions. UAVs can also include cargo bays, hooks, or other means forcarrying payloads.

Newer generation UAVs can also provide significant payload capabilities.As a result, UAVs can also be used for delivering packages, groceries,mail, and other items. The use of UAVs for deliveries can reduce costsand increase speed and accuracy. However, landing a UAV at a deliverylocation may be problematic for multiple reasons, such as the presenceof obstacles (e.g., trees, power lines, etc.) and the power requirementsof descending and ascending from the delivery location, among otherreasons.

DETAILED DESCRIPTION

Examples of the present disclosure relate generally to shipping labels,and specifically to a shipping label parachute system to enable thedelivery of packages by unmanned aerial vehicles (“UAVs”) or otheraerial vehicles. The shipping label parachute system can function as aconventional shipping label and can attach to packages in a conventionalmanner, but can include parachute components to enable packages to besafely dropped from UAVs, or other aerial vehicles, for delivery. Theshipping label parachute system can comprise multiple sizes for deliveryof different weight and size packages.

As discussed above, improvements in battery and propulsion systemcomponents, among other things, have increased the payload capacity andrange of many UAVs. As a result, local delivery of packages and otherobjects via UAV has become practical. As a result, it may be desirableto have a system and method to enable a package to be dropped from aUAV, or other aerial vehicle, yet have its descent controlled by aparachute, or similar. The system preferably enables the workflowprocess of shipping and handling to remain substantially unchanged. Thesystem is preferably compact, self-contained, and relativelyinexpensive.

To this end, examples of the present disclosure can comprise a shippinglabel parachute system. The system can comprise a parachute folded tohave substantially the same planform as a conventional shipping label.The parachute can be inserted into a packet or envelope comprising anadhesive backing, or similar, to enable the system to be easily attachedto a package for delivery. In some examples, the adhesive backing canprovide sufficient adhesion between the system and the package to remainattached to the package upon deployment of the parachute and thesubsequent descent. The parachute system can include a number ofadditional features including, but not limited to, a shock absorber,additional identifying features, and a clear, breakaway cover. Thepackages can be delivered by a UAV, which can include cameras and othersensors to monitor the route if the UAV and the descent of the package,among other things.

As shown in FIG. 1, examples of the present disclosure can comprise amethod 100 for delivering packages via a UAV. At 102, a shipping labelparachute system 104 can be affixed to a shipping container 106 in theconventional manner. As used herein, the term “shipping container”includes any container used to secure a package, including aconventional cardboard or paper box, but also a soft-sided container, abag, an envelope, a shipping pouch, cooler, or any other type of rigidor non-rigid container. In some example, the shipping label parachutesystem 104 can include an adhesive backing to couple or affix theshipping label parachute system 104 to the shipping container 106. Inother examples, the shipping label parachute system 104 can be affixedto the shipping container 106 using crimp-on straps, weld-on straps,cables ties, or other means. As discussed below, the shipping labelparachute system 104 can include, for example, an adhesive back, aparachute, a breakaway cover, and a static line.

At 108, the shipping container 106, with the shipping label parachutesystem 104 attached, can be attached to a UAV 110. In some examples, theUAV 110 can include retractable arms, claws, suction cups, pins, hooks,adhesive, or other means to retain the shipping container 106. In someexamples, the shipping label parachute system 104 can include straps, orother means, to attach the shipping container 106 to the UAV 110. Insome examples, the shipping label parachute system 104 can include astatic line attached to the parachute and the UAV 110 to facilitate theopening of the parachute.

At 112, upon arrival at the delivery location 114, the UAV 110 can dropthe shipping container 106, thereby deploying the parachute 116. Theparachute 116, sometimes in conjunction with the packing material usedin the shipping container 106, can enable the contents of the shippingcontainer 106 to be delivered undamaged. In this manner, the UAV 110 canalso remain at a safe distance and height from the delivery location114, reducing the chances of a collision between objects and other itemsat the delivery location 114.

FIG. 2 depicts the shipping label parachute system 104 in the deployed(i.e., parachute open) position. As shown, the shipping label parachutesystem 104 can comprise a backing sheet 202 and a breakaway cover 204.In some examples, the backing sheet 202 can comprise, for example, paperor plastic. In some examples, the backing sheet 202 can also include anadhesive backing to enable the shipping label parachute system 104 to beattached to the shipping container 106. In other examples, the backingsheet 202 can be attached to the shipping container 106 using boxstaples, straps, or other suitable means. In still other means, thebacking sheet 202 can include hooks, claws, or other mechanical means toattach the shipping label parachute system 104 to the shipping container106.

The shipping label parachute system 104 can also include a parachutesystem 206. The parachute system 206 can comprise a parachute canopy208. The parachute canopy 208 can comprise a suitably light, strongmaterial such as, for example, paper, plastic, canvas, silk, nylon,Kevlar®, polyester, or combinations thereof. In some examples, differentsized parachute canopies 208 can be used for different sized shippingcontainers 106. The parachute canopies 208 can be sized and shaped toslow a shipping container's 106 descent appropriately to prevent damageto the contents of the shipping container 106. The parachute canopy 208can be sized according to the weight, size, and/or shape of the shippingcontainer 106 and contents.

In some examples, the parachute canopy 208 may be the same size forshipping containers 106 of the same weight. In other examples, theparachute canopy 208 may be sized differently for shipping containers106 of the same weight based on the contents. In other words, a shippingcontainer 106 carrying a drinking glass may have a larger parachutecanopy 208 than a shipping container 106 carrying a screwdriver simplybecause the glass is more fragile than the screwdriver and thus, has alower predetermined landing speed.

Although shown as a conventional, round parachute canopy 208, othercanopy shapes could be used. Square or ram air parachute canopies 208can be used, for example, to enable the package to travel apredetermined distance, for example, when dropped. In other words,rather than traveling substantially vertically downward when deployed,as with the round canopy 208, a square canopy 208 may be used, forexample, to provide a predetermined “stand-off” distance for the UAV110. In this manner, the package could be dropped from a predeterminedheight and distance from the delivery location 114 and glide forward anddownward to the delivery location 114 based on the standard glideslopeof the canopy 208.

While described above as a parachute canopy 208, other arresting devicescan be used. The parachute canopy 208 can comprise a streamer, forexample, such as those used in model rocketry. The parachute canopy 208can also comprise an auto-rotating propeller, or similar device. Anumber of additional devices designed to slow the package to thepredetermined landing speed could be used and are contemplated herein.

The parachute canopy 208 can be connected, directly or indirectly, tothe shipping label parachute system 104 via a plurality of parachutecords 210. The parachute cords 210 can comprise a sufficiently strongmaterial to withstand the opening of the parachute canopy 208 and tosupport the weight of the shipping container 106. The parachute cords210 can comprise, for example, nylon, cotton, polyester, Kevlar®, orcombinations thereof. In some examples, as discussed below, theparachute cords 210 can connect directly to the shipping label parachutesystem 104.

In other examples, the parachute cords 210 can connect to the shippinglabel parachute system 104 via a harness 212 and/or a shock absorber214. In some examples, the harness 212 can comprise a spreader bar 212 aand one or more attachment points 212 b for the parachute cords 210. Theharness 212 can comprise, for example, plastic, cardboard, aluminum,composite, or combinations thereof. The harness 212 can help separatethe parachute cords 210 to prevent tangling of the cords 210 duringpacking and deployment.

The harness 212 can also prevent twisting between the parachute canopy208 and the shipping container 106 upon deployment, for example, andduring the descent of the shipping container 106. The harness 212 canalso reduce deployment time of the parachute canopy 208 by spreading theparachute cords apart and can help prevent failed deployment orpartially failed deployment (e.g., “streamers”). While shown as aspreader bar 212 a, the harness 212 can comprise many shapes including,but not limited to, circular, ovoid, and rectangular that enable theparachute cords 210 to connect at multiple locations. In some examples,the harness 212 can also comprise multiple pieces.

In other examples, the parachute cords 210 can connect directly to theshipping label parachute system 104 without a harness 212. In thismanner, the parachute cords 210 can be attached directly to the backingsheet 202, for example, or sandwiched between the backing sheet 202 andthe shipping container 106. The harness 212 may be unnecessary forsmaller canopies 208, for example, or for packages using multipleshipping label parachute systems 104. Removal of the harness 212 canenable the parachute cords 210 to be connected directly to the shippinglabel parachute system 104 and may reduce the stowed size and weight ofthe system 104 as well as the cost of the system 104.

In some examples, a shock absorber 214 can be disposed between theparachute canopy 208 and the shipping label parachute system 104. Theshock absorber 214 can absorb the shock of opening the parachute canopy208 and can help prevent separation of the parachute canopy 208 from theshipping container 106, damage to contents, and breakage of parachutecords 210, among other things. This can be achieved by preventing thebacking sheet 202 from pulling free from the shipping container 106, forexample.

The shock absorber 214 can take many forms designed to absorb shock andreduce peak loads by increasing the time interval of a shock event suchas the canopy 208 opening. The shock absorber 214 can comprise, forexample, one or more strips, strings, or tubes of material in line withthe parachute cords 210. The shock absorber 214 can comprise a number ofstrong, resilient materials including, but not limited to, plastic,rubber, elastic, nylon, or combinations thereof. The shock absorber 214can also comprise metal or plastic springs and other biasing devicesconfigured to absorb energy. The shock absorber 214 can also comprisetear-away energy absorbing devices that absorb energy through thetearing of material, stitches, or adhesive similar to “screamers” usedin mountain climbing, for example. The shock absorber 214 can alsocomprise one or more concentric tubes with a hydraulic or pneumaticvalving system similar to vehicle shock absorbers.

In some examples, a first portion 210 a of the parachute cords 210 canbe attached to the parachute canopy 208 on one end and then to a firstend 214 a of the shock absorber 214 on the other. In this configuration,a second end 214 b of the shock absorber 214 can be attached directly tothe backing sheet 202 and/or the shipping container 106. In otherexamples, as discussed in greater detail below with reference to FIG.2C, the shock absorber 214 can be disposed in a middle section of theparachute cords 210, with the first portion 210 a of the parachute cords210 attached at one end to the first end 214 a of the shock absorber 214and a second portion 210 b of the parachute cords 210 attached at oneend to the second end 214 b of the shock absorber 214 and attached atthe other end to the backing sheet 202 and/or shipping container 106.

In some examples, the parachute system 206 can further comprise a staticline 216. As with larger parachutes, the static line 216 can be attachedto the delivery vehicle (e.g., a UAV 110) to enable the parachute canopy208 to open more quickly upon deployment. This can help to preventdeployment failure and streamers, among other things.

In some examples, the static line 216 can be detachably coupled to theparachute canopy 208 such that, upon deployment, the static line 216pulls the parachute canopy 208 open, but then detaches from theparachute canopy 208 and remains attached to the UAV 110. In thisconfiguration, the static line 216 may be sewn or taped to the parachutecanopy 208 with a thread or tape, for example, which provides sufficientstrength to pull the parachute canopy open 208, but then breaks underthe weight of the shipping container 106.

In other examples, the reverse may be true, with the static line 216coupled to the parachute canopy 208 and detachably coupled to the UAV110 such that, upon deployment, the static line 216 pulls the parachutecanopy 208 open, yet remains attached to the parachute canopy 208 anddetaches from the UAV 110. In this configuration, the static line 216may have a loop sewn into one end, which provides sufficient strength topull the parachute canopy open 208, but then breaks under the weight ofthe shipping container 106. Similarly, the static line 216 can beattached to a spring-loaded hook, pincer, or loop on the UAV 110 thatprovides sufficient resistance to open the parachute canopy 208, butthen moves or opens to release the static line 216 under the weight ofthe shipping container 106. In some examples, the static line 216 may bebiodegradable, photodegradable, water soluble, or otherwise safelydisposable to enable the UAV 110 to drop the static line 216 at somepoint during its return to the distribution center, for example.

As shown in FIG. 3A, the shipping label parachute system 104 cancomprise a number of components that can be flat packed into anenvelope-like package. In this manner, the shipping label parachutesystem 104 can be attached to the shipping container 106 in theconventional manner, much like a standard shipping label. In someexamples, the shipping label parachute system 104 can be attached to theshipping container 106 using the same workers and/or machines as“normal” shipping labels, such that the shipping and handling process isessentially unchanged (until delivery begins, as discussed below). Inthis manner, as discussed below, the shipping label parachute system 104can include the necessary shipping and handling information such thatall shipping containers 106 can include the parachute system 206regardless of whether they are being delivered by UAV 110. In thismanner, the delivery method can be chosen at the time of delivery,rather than during the packing process. This may be useful to accountfor variable weather conditions, demand, cost, darkness, or othervariables in the shipping process.

In some examples, the shipping label parachute system 104 can includethe aforementioned backing sheet 202. The backing sheet 202 can act asthe base for the shipping label onto which the other components areassembled. In some examples, the backing sheet 202 can also include aprotective sheet 302 applied to the first side of the backing sheet 202.The protective sheet 302 can comprise, for example, waxed paper, paper,or plastic. The protective sheet 302 can be used when, for example, thebacking sheet 202 includes an adhesive on the first side. In thismanner, the protective sheet 302 can be removed from the first side ofthe shipping label parachute system 104 and the shipping label parachutesystem 104 can be quickly and easily applied to the shipping container106.

In some examples, the backing sheet 202 can include a separate adhesivesheet 304. In this configuration, the second side of the adhesive sheet304 can be adhered to the first side of the backing sheet and theprotective sheet 302 can be applied to the adhesive sheet 304. Similarto the configuration above, in this configuration, the protective sheet302 can be removed from the adhesive sheet 304 and the shipping labelparachute system 104 can be quickly and easily applied to the shippingcontainer 106.

The shipping label parachute system 104 can also include a plurality ofparachute cords 210. The first portion 210 a of the parachute cords 210can be attached to the parachute canopy 208, while the second portion210 b can be attached to the backing sheet 202 or the shipping container106. In some examples, as discussed above, the parachute cords 210 canalso include a shock absorber 214.

In some examples, the second portion 210 b of the parachute cords 210can be disposed through a first aperture 306 in the backing sheet 202.In this manner, the second portion 210 b of the parachute cords 210 canbe sandwiched between the backing sheet 202 and the shipping container106 when the shipping label parachute system 104 is attached to theshipping container 106. In other examples, the second portion 210 b ofthe parachute cords 210 can be sandwiched between the backing sheet 202and the adhesive sheet 304. In other examples, the second portion 210 bof the parachute cords 210 can be sandwiched between the adhesive sheet304 and the shipping container 106. Regardless of configuration, theparachute cords 210 can be prevented from pulling out of the shippinglabel parachute system 104 by both friction (i.e., between shippinglabel parachute system 104 and the shipping container 106) and adhesive.

The parachute canopy 208 can be folded such that it fits in the same, orsmaller, area as required for the backing sheet 202. In some examples,the parachute canopy 208 can be folded radially and/or laterally to fitin the required planform. In some examples, the parachute canopy 208 caninclude a data label 308. The data label 308 can include, for example,address information, quick response (QR) codes, bar codes, or otherinformation. In this configuration, the parachute canopy 208 can befolded such that the data label 308 is visible when the shipping labelparachute system 104 is attached to the shipping container 106.

The shipping label parachute system 104 can further comprise a breakawaycover 204. The breakaway cover 204 can comprise, for example, paper orplastic and can be designed to “break away,” or tear open, upondeployment of the parachute system 206. In some examples, the breakawaycover 204 can comprise, for example, clear plastic or cellophane toenable the data label 308, or other components, to be visible when theshipping label parachute system 104 is in the stowed position. In someexamples, the breakaway cover 204 can include one or more perforations310 to enable the breakaway cover 204 to tear in a controlled mannerupon deployment of the parachute system 206. The perforations 310 caninclude actual perforations in the breakaway cover 204, score lines, ormolded thinner areas, for example, to enable the breakaway cover 204 totear in a controlled manner.

The shipping label parachute system 104 can also comprise the staticline 216 to aid the deployment of the parachute canopy 208. As discussedabove, the static line 216 can be attached to the parachute canopy 208such that it detaches from the parachute canopy 208 and remains with theUAV 110, or vice-versa. In some examples, the static line 216 can bedisposed through a second aperture 312 the breakaway cover 204. In thismanner, the static line 216 can be attached to the UAV, along with theshipping container 106, for delivery, with the shipping label parachutesystem 104 still in the stowed position.

FIG. 4 is a detailed view of the harness 212 and shock absorber 214components of the parachute system 206. As mentioned above, in someexamples, the first portion 210 a of the parachute cords 210 can beattached to, or run through, a harness 212, or spreader. The harness 212can help prevent the tangling of the parachute cords 210 during packingand deployment. The harness 212 can also prevent tangling of theparachute cords 210 during descent by substantially preventing theshipping container 106 from spinning with respect to the parachutecanopy 208. As shown, in some examples, the harness 212 can include oneor more harness apertures 402 to enable the parachute cords 210 to berouted through the harness and down toward the backing sheet 202.

In other examples, the parachute cords 210 can be attached to thespreader bar 212 a of the harness 212, rather than running through it.In this manner, a portion of the parachute cords 210 c can be attachedto the top of the spreader bar 212 a, while another portion 210 b can beattached to the bottom of the spreader bar 212 a and the shock absorber214, discussed below. The parachute cords 210 can be mechanicallyaffixed (e.g., tied, fastened, or adhered) to the spreader bar 212 a. Insome examples, the spreader bar 212 a can include a plurality ofeyelets, or other means, for this purpose.

In some examples, the parachute system 206 can also include a shockabsorber 214. The shock absorber 214 can be disposed between theparachute canopy 208 and the shipping container 106 to absorb the shockof the initial opening of the parachute canopy 208 and bouncing, orother disturbances, during descent. In some examples, one end of thefirst portion 210 a of the parachute cords 210 can be attached to theparachute canopy 208 and the other end can be attached to a first end214 a of the shock absorber 214. In this configuration, a second end 214b of the shock absorber 214 can be attached to the backing sheet 202and/or the shipping container 106 (not shown).

As shown in FIG. 3B, in some examples, rather than using a static line216, the shipping label parachute system 104 can use an adhesive staticline system 314. In this configuration, the parachute canopy 208 cancomprise an adhesive patch 316. The adhesive patch 316 can comprise, forexample, an adhesive sheet, similar to the adhesive sheet 304 used onthe backing sheet 202. In other examples, the adhesive patch 316 cancomprise a hook and loop material, for example, or other materialcapable of creating an adhesive force sufficient to pull the parachutecanopy 208 open when the shipping container 106 is dropped.

In some examples, the breakaway cover 204 can comprise a window 318 toenable contact between the adhesive patch 316 and the UAV 110. In thismanner, when the UAV 110 drops the package, the adhesive patch 316 canact like a static line 316. In other words, the adhesion between theadhesive patch 316 and the UAV 110 can be sufficient to open theparachute canopy 208, while still allowing the package to drop free ofthe UAV 110 afterwards. The adhesive static line system 314 can open theparachute canopy 208, while obviating the need for a static line 216 andthe need to attach the static line 216 to the UAV 110 during packagingand/or recover the static line 216 after use. This can decrease handlingtime when shipping a package and can address any possible issuesintroduced by the recovery and/or entanglement of static lines 216.

In other examples, as shown in FIG. 4, the shock absorber 214 can bedisposed in a middle portion of the parachute cords 210. In other words,the parachute cords 210 can be cut in the middle and the shock absorber214 can be inserted between the first portion 210 a and the secondportion 210 b of the parachute cords. Thus, the one end of the firstportion 210 a of the parachute cords 210 can be attached to theparachute canopy 208 and the other end attached to one end of the shockabsorber 214. The second portion 210 b, in turn, can be attached on oneend to the other end of the shock absorber 214 and on the other end tothe backing sheet 202 and/or the shipping container 106.

In this manner, the shock absorber 214 can be added during manufacture,as necessary, without disturbing the basic architecture of the parachutesystem 206. In other words, for some shipping label parachute systems104, the parachute cords 210 can be attached directly to the backingsheet 202 and/or the shipping container 106, for example; while, inother cases, the parachute cords 210 can be cut in the middle and theshock absorber 214 can be inserted. The shock absorber 214 can bewelded, stapled, or adhered (e.g., using epoxy, hot glue, etc.) to theparachute cords 210.

In still other examples, the function of the shock absorber 214 can beincluded in the parachute cords 210. In other words, in some examples,the parachute cords 210 can contain sufficient elasticity to serve thefunction of the shock absorber 214 to obviate the need for a separateshock absorber 214. Similarly, as discussed above, in some instances theharness 212 may be unnecessary. To this end, in some examples, theparachute cords 210 can be attached to the backing sheet 202 and/or theshipping container 106 as shown, while in other cases, the parachutecords 210 can be attached to the backing sheet 202 and/or the shippingcontainer 106 in multiple locations to effectively serve as a harness212. In other examples, such as on relatively small parachutes (e.g.,for small, light shipping containers 106), for example, the function ofthe harness 212 may simply be unnecessary enabling the attachment of allparachute cords 210 to a single location on the backing sheet 202 and/orthe shipping container 106.

As shown in FIG. 5, in some examples, the parachute canopy 208 cancomprise a number of additional identifying features including, but notlimited to, QR codes 502, bar codes 504, patterns 506, warning labels508, and/or address labels 510. In some examples, the parachute canopy208 can be folded such that one or more of these identifying features isvisible through the breakaway cover 204 when the parachute system 206 isin the stowed position. In this manner, the parachute canopy 208 canserve as the bill of lading, for example, or can provide the address,shipping information, or other information, for the package while theparachute system 206 is in the stowed position. In other words, one ormore of the identifying features can be visible through the breakawaycover 204 in the stowed position.

In some examples, the parachute canopy 208 can comprise, for example,one or more QR codes 502 and/or bar codes 504. The QR codes 502 and/orbar codes 504 can include information related to the parachute system206 (e.g., maximum weight and/or size capacities), for example, theshipping container 106, the contents of the shipping container 106, theshipping center, and/or the delivery address of the shipping container106. In some examples, the QR code 502 can include information relatedto the maximum payload for the parachute system 206, for example. Inthis manner, as the shipping container 106 is being prepared forshipment and weighed, the QR code 502 can confirm that the correctshipping label parachute system 104 has been affixed to the shippingcontainer 106 for the weight of the package.

In some examples, the parachute canopy 208 can also include one or morepatterns 506. In some examples, the patterns 506 can comprise ageometric, random, or other pattern to enable measurement of themovement of the parachute system 206 upon deployment. In some examples,the pattern 506 can be viewed by a camera, or other detection device, onthe UAV 110 to detect the spin and/or descent rate of the parachutecanopy 208, for example, as is descends. In this manner, if therecipient of package claims that the package, equipment on the ground,people or animals were adversely impacted during delivery, for example,the manner in which the package descended can be reviewed to determineif the descent was the cause of the damage.

In some examples, the parachute canopy 208 can also include one or morewarning labels 508. The warning labels 508 may include warnings aboutchoking or suffocation, similar to a dry-cleaning bag, for example, orregarding the proper disposal of the parachute canopy 208 (e.g.,recycling information). Finally, the parachute canopy 208 can alsoinclude an address label 510. The address label 510 can include thereturn and destination address, for example, the method of shipment, andthe weight of the shipping container 106. In some examples, the addresslabel 510 can also include tracking bar codes, or other information,relevant to shipping the package.

In still other examples, the parachute canopy 208 can include one ormore advertisements, flyers, or other marketing materials. In someexamples, the parachute canopy 208 can comprise coupons, for example, toencourage additional orders from the delivery customer. In otherexamples, the parachute canopy 208 can include “deals of the day (orweek).” In still other examples, targeted advertising space can be soldon the parachute canopies 208. In other words, based on the recipient'sorder, advertising can be included on the parachute canopy 208 focusedtoward the recipient's apparent interested based on the current order.

As shown in FIG. 6A, in some examples, the shipping label parachutesystem 104 may be adhered to the shipping container 106 using a suitabletape or adhesive. In this configuration, the tape or adhesive can be ofsufficient strength to maintain the connection between the parachutesystem 206 and the shipping container. In this manner, the shippinglabel parachute system 104 with the parachute system 206 can simply beattached to the shipping container 106 in the same manner as aconventional shipping label.

As shown in FIG. 6B, in other examples, the shipping label parachutesystem 104 may be attached to the shipping container 106 using one ormore straps 602 and fasteners 604. In some examples, the straps 602 maybe conventional polypropylene or steel straps and the fasteners 604 canbe conventional crimp connectors. In this manner, the shipping labelparachute system 104 can be attached to the shipping container usingconventional packaging equipment. In still other examples, the shippinglabel parachute system 104 can include barbs, staples, or other meansinstead of, or in addition to, the aforementioned adhesives and strapsto mechanically attach the shipping label parachute system 104 to theshipping container 106.

In some examples, as shown in FIGS. 6A and 6B, the shipping labelparachute system 104 can also include one or more shipping labels 606,608. In some examples, the shipping labels 606, 608 can be applied to atop surface of the breakaway cover 204. In other examples, the shippinglabels 606, 608 can be placed below the breakaway cover 204 and bevisible through the clear breakaway cover 204. In still other examples,the shipping labels 606, 608 can be printed on the parachute canopy 208.In this configuration, the parachute canopy 208 can be folded such thatthe shipping labels 606, 608 are visible through the breakaway cover 204in the stowed position.

In some examples, the shipping labels 606, 608 can be adhered to thebreakaway cover 204 such that they can be easily peeled off (e.g., usinga removable adhesive). In this manner, a first shipping label 606 cancontain shipping information for a first mode of transportation, forexample, and a second shipping label 608 can contain shippinginformation for a second mode of transportation. In this manner, themode of shipping can be selected at the actual point of shipping bysimply removing the shipping label 606, 608 for the appropriate (e.g.,non-selected) shipping mode. As discussed below, this can enable themode of transportation to be selected at the time of shipping based ondemand, weather, weight, and cost, among other things.

As shown in FIGS. 7A and 7B, in some examples, the parachute cords 210can be used to secure the parachute system 206 to the shipping labelparachute system 104 and/or the shipping container 106. As discussedabove, in some examples, the backing sheet 202 can include adhesive onone side. In some examples, the backing sheet 202 can include a separateadhesive sheet 304. In other examples, the adhesive can simply beapplied to the first side of the backing sheet 202.

Regardless, as shown in FIG. 7A, in some examples, the parachute cords210 can be inserted through the first aperture 306 in the backing sheet202 and then splayed in a substantially radial manner. When the shippinglabel parachute system 104 is applied to the shipping container 106,therefore, the parachute cords 210 can be trapped between the backingsheet 202 and the shipping container 106 and further secured by theadhesive (or adhesive sheet 304). In this manner, the surface contactbetween the ends of the second portion 210 b of the parachute cords 210and the backing sheet 202 is increased, increasing the force required topull the parachute cords 210 out during deployment and descent.

Similarly, as shown in FIG. 7B, the second portion 210 b of theparachute cords 210 can be arranged in a spiral pattern. This canfurther increase the surface contact between the ends of the parachutecords 210 and the backing sheet 202. This may be useful for particularlyheavy boxes, for example, that use larger parachute canopies 208 andthus, place additional stress on the parachute cords 210. This may alsobe useful for smaller parachute canopies 208 that, in turn, use smallerparachute cords 210, simply to increase the contact area between theparachute cords 210 and the backing sheet 202 and/or shipping container106.

In still other examples, as shown in FIG. 7C, the shipping labelparachute system 104 may be attached to the shipping container 106 usingone or more straps 602 and fasteners 604. As mentioned above, in someexamples, the straps 602 may be conventional polypropylene or steelstraps and the fasteners 604 can be conventional crimp connectors. Inthis configuration, the parachute cords 210 can be attached to thestraps to provide a mechanical connection to the shipping container 106.

In some examples, the parachute cords 210 can be tied to the straps 602.In other examples, the parachute cords 210 can be attached to the straps602 using cable, or “zip,” ties 702, staples, twist ties, or othersuitable means. In still other examples, the parachute cords 210 may beglued to the straps 602 during assembly of the shipping label parachutesystem 104. In yet other examples, the parachute cords 210 may bestapled to the shipping container 106 prior to attaching the adhesivesheet 304 to the shipping container 106. In any of these configurations,the shipping label parachute system 104 is provided with a mechanicalbond, an adhesive bond, or both between the parachute cords 210 and theshipping container 106 further reducing the likelihood the parachutecords 210 pulling away from the shipping container 106 during thedescent.

As discussed above, shipping containers 106 using shipping labelparachute system 104 can be delivered using a variety of aerial vehiclesincluding, but not limited to, airplanes, helicopters, and UAVs. Anon-limiting example of a UAV is shown in FIG. 8A. In some example, theUAV 110 can include an onboard propulsion system 802, which can includeone or more motors or engines 804 driving propellers 806. The UAV 110can include the required processing and navigation power to receiveinstructions and travel from a pick-up location (e.g., a shipping ordistribution location) to the delivery location (e.g., a home orbusiness). In some examples, the UAV 110 may simply receive“turn-by-turn” directions from a central control system.

The UAV 110 can carry the shipping container 106 in a number of ways. Insome examples, as shown, the UAV 110 can include mechanical arms 808 togrip the shipping container 106 on the sides. In other examples, the UAV110 can include, for example, a suction system, magnet, or retractableshelf to carry the shipping container 106. In still other examples, theshipping container 106 can include straps 602, handles, loops, hooks,Velcro®, or other means to enable the UAV 110 to carry the shippingcontainer 106.

In some examples, the UAV 110 can also include a hook 810 for engagementwith the static line 216 (when applicable). As discussed above, the hook810 can provide the necessary pulling force on the static line 216 toopen the parachute canopy 208 when the shipping container 106 is droppedfrom the UAV 110. In some example, the static line 216 can detach fromthe parachute canopy 208 and remain on the hook 810. In this manner, thestatic line 216 can be returned to the distribution location for reuse,recycling, or disposal.

In other examples, the hook 810 can be spring-loaded. In this manner,when the shipping container 106 is dropped, the hook 810 provides thenecessary tension to deploy the parachute canopy 208, but then pivotsdownward under the weight of the shipping container 106 to release thestatic line 216. In this manner, the static line 216 can remain with theshipping container 106, reducing drag and the possibility ofentanglement with the UAV 110, among other things. Although shown anddescribed as a hook, the hook 810 can also comprise other mechanical orelectro-mechanical means for holding the static line 216 such as, forexample, a snap ring, pincer, or servo designed to retain the staticline 216 until deployment.

The UAV 110 can further comprise a sensor system 812. In some examples,the sensor system 812 can comprise one or more cameras. The UAV 110 caninclude a camera, for example, for use during navigation and to enablethe UAV 110 to record and/or analyze the descent of the shippingcontainer 106, among other things. In some examples, the sensor system812 can also be used to verify, for example, the descent path, landinglocation, and attitude of the package on the ground (e.g., to determineif the package landed on its side). In some examples, the sensor system812 can also be used to verify addresses, locate landmarks, relaytraffic information, etc.

In some examples, the sensor system 812 can comprise stereoscopiccameras, for example, to enable the system to calculate the positionand/or descent rate of the shipping container 106 after deployment. Inother examples, the sensor system 812 can include, for example, radar orsonar sensors for this purpose. In this manner, if a package is damagedduring delivery, the descent of the package from the UAV to the deliverylocation can be confirmed or eliminated as the source of the damage. Insome examples, the sensor system 812 can work in concert with patterns506 disposed on the parachute canopy 208 to determine descent rate,descent angle, and spin of the parachute canopy 208, among other things.

As discussed above, and shown in FIG. 8B, in some examples, the shippinglabel parachute system 104 can comprise an adhesive static line system314. In this configuration, an adhesive patch 316 can be in contact witha surface 814 on the UAV 110. As the name implies, the adhesive patch316 can literally be a piece of adhesive paper, or other sticky surface,configured to stick to the surface 814 of the UAV 110. In otherexamples, the adhesive patch 316 can comprise a hook and loop materialwith a complementary hook and loop material disposed on the surface 814of the UAV 110. Regardless of the configuration, the adhesive strengthbetween the adhesive patch 316 and the surface 814 is preferably strongenough to pull open the parachute canopy 208, but weak enough to releaseunder the weight of the package. In this manner, the opening of theparachute canopy is expedited, yet there is no static line 216 toretrieve and/or dispose of.

As shown in FIG. 9, examples of the present disclosure can also comprisea method 900 for preparing a package for shipment by a UAV. As shown,because the planform of the shipping label parachute system 104 issubstantially similar to that of a conventional shipping label, much ofthe shipping and handling process for a package can remain unchangedfrom convention practices. At 902, for example, the item(s) 904 to bedelivered can be placed in the shipping container 106. Of course, thesize of the shipping container 106 can be determined based on the sizeand weight of the item(s) 904. In some examples, a variety of shippingcontainers 106 with predetermined size and weight constraints can bepaired with appropriately sized shipping label parachute systems 104(and thus, parachute systems 206).

At 906, appropriate packing material 908 can be placed in the shippingcontainer 106 with the item(s) 904. In some examples, the packingmaterial 908 can comprise conventional packing materials such as, forexample, “packing peanuts,” inflatable bladders, foam, or Styrofoamsheets. In other examples, the packing materials 908 can be selectedbased on the parachute system 206 employed. In other words, the packingmaterials 908 can be chosen to match the rate of descent of a particularparachute system 206. In this manner, the packing materials 908 and theparachute system 206 can comprise a complementary system for protectingthe item(s) 904 during delivery. In some examples, different packingmaterials can be used for delivery by UAV than by conventional deliverymethods.

At 910, the shipping container 106 can be sealed in an appropriatemanner using, for example, tape and the shipping label parachute system104 can be applied to the shipping container 106. Because the shippinglabel parachute system 104 has a similar planform to a conventionalshipping label (i.e., one that provides, for example, a bill of ladingor address information), it can be applied to the shipping container 106in a conventional manner. When the shipping label parachute system 104has an adhesive backing, for example, the user can simply remove theprotective sheet 302 (e.g., waxed paper) and apply the shipping labelparachute system 104 to the shipping container 106.

At 912, the user can determine the appropriate mode of delivery. If theweather is unfavorable for delivery by UAV 110, for example, the usermay choose to deliver the package by conventional means such as, forexample, by truck 914. Unfavorable conditions for delivery can include,for example, times of high demand, high winds, or heavy rain that makedelivery by UAV 110 expensive, difficult, dangerous, or impossible. At916, upon determining the mode of delivery, the shipping label 606 forthe non-selected mode of delivery can be removed, with the applicableshipping label 608 left in place. In this manner, only informationrelevant to the chosen mode of delivery (e.g., by UAV 110) remains onthe shipping container 106 to avoid confusion. In some examples, theshipping label 606 may include information related to both forms ofshipment on a single label. In this configuration, removal of the“extra” shipping label is obviated.

At 918, the shipping container 106 can be attached to the UAV 110. Asdiscussed above, this can be done using a number of appropriate meansincluding, but not limited to, cargo hooks, cargo bays, pincers,mechanical arms, magnets, suction cups, or retractable shelves. At 920,the static line 216 (if used) can be attached to the hook 810 on the UAV110. The package is now ready for delivery by the UAV 110.

As shown in FIGS. 10A and 10B, examples of the present disclosure canalso comprise a method 1000 for delivering a package via UAV. As shownin FIG. 10A, at 1002, the UAV 110, having been previously loaded withone or more shipping containers 106 can receive routing information froma central control 1004. In some examples, the central control 1004 canbe connected via a wireless or wired connection to the UAV 110 toprovide routing instructions. In some examples, as shown, the centralcontrol 1004 can be connected to the UAV 110 via a cellular connection1006 to enable the central control 1004 and the UAV 110 to remain incommunication during all, or most, of the UAVs 110 flight.

In some examples, the UAV 110 can include onboard navigation viacellular or global position system (GPS) signals, for example. In thisconfiguration, the central control 1004 may simply send an address orGPS coordinates to the UAV 110. In this configuration, the UAV 110 canbe capable of flying the received route autonomously orsemi-autonomously. In other examples, the navigational computations maybe provided by the central control 1004, with the central control 1004providing “turn-by-turn” directions to the UAV 110.

At 1008, the UAV 110 can activate its propulsion system and take off. At1010, the UAV 110 can navigate the route from the distribution location(e.g., a distribution or shipping center) to the delivery location 114.As discussed above, the UAV 110 may navigate using, for example,cellular location services, GPS, the onboard sensors, or a combinationthereof. In some examples, the UAV 110 may provide status updates to thecentral control 1004 and/or receive location updates from the centralcontrol 1004 en route.

At 1012, the UAV 110 can determine if it has reached the deliverylocation 114. In some examples, the UAV 110 can verify that it hasreached the delivery location 114 using cellular location or GPScoordinates. In other examples, the UAV 110 can periodically send itscurrent location to the central control 1004. In this configuration, thecentral control 1004 can provide directions to the UAV 110 and informthe UAV 110 when it has reached the delivery location 114. In someexamples, the UAV 110 can determine (or verify) it has reached thedelivery location 114 using the sensor system 812. This can includeviewing local signage and/or the address on a house or mailbox with anonboard camera, for example.

As shown in FIG. 10B, at 1016, the UAV 110 can activate the sensorsystem 812 (if it is not already active) to record the descent of thepackage from the UAV 110 to the ground at the delivery location 114. Asdiscussed above, this can include recording video footage, includingstereoscopic video footage, of the package as it descends from the UAV110. The descent of the package may also be measured using radar, sonar,or other sensors, as desired, to provide additional data. In someexamples, the sensor system 812 may be activated during the entireflight.

The descent of the shipping container 106 can be recorded to provideinformation related to, for example, the deployment of the parachutesystem 206, the descent speed, direction, and spin. The descent of theshipping container 106 can be recorded to verify the landing location atattitude of the shipping container 106 and to ensure that the shippingcontainer 106 did not collide with people, vehicles, or other objects onthe ground. This can be useful to determine if damage reported to theshipping container 106 (or contents 904) or by the shipping container106 is valid, to determine the cause, and to take remedial action, asnecessary.

At 1018, the UAV 110 can drop the package. In some examples, the UAV 110may ascend or descend to a predetermined height to drop the shippingcontainer 106 to ensure proper parachute system 206 deployment. In someexamples, different sized parachute systems 206 may have differentminimum height requirements based on the size of the parachute canopy208, the weight of the shipping container 106, wind conditions, etc. Asdiscussed above, dropping the shipping container 106 may also cause thedeployment of the parachute system 206 via the static line 216. Thesensor system 812 can monitor the descent of the shipping container 106from the UAV 110 to the ground at the delivery location 114.

At 1020, in some examples, the UAV 110 can verify that the shippingcontainer 106 is safely on the ground. This can include verifying zerovelocity using the sensor system 812, for example, or by verifying thatthe parachute canopy 208 is lying slack on the ground. In some examples,the UAV 110 may send sensor data or pictures to the central control 1004for verification by a central control 1004 computer or worker.

In some examples, the UAV 110 and/or the central control 1004 cancompare the current altitude of the UAV 110 and the distance from theUAV 110 to the shipping container 106 to ensure the shipping container106 has safely reached the ground. If the shipping container 106 hasbeen caught in a tree or landed on the roof, for example, the UAV 110can determine that the shipping container 106 is still above groundlevel and send a message to the central control 1004.

The message can enable the central control 1004 to log an anomaly and/orsend support staff to the delivery location 114 to retrieve orreposition the package, as necessary. This can also enable the supportstaff to assess any damage to the shipping container 106 and/or thedelivery location 114 and proactively take appropriate action. In someexamples, the sensor system 812 can also verify that the shipping labelparachute system 104 is facing up, indicating that the shippingcontainer 106 has landed upright. This may be done by verifying that thebacking sheet 202, for example, is visible from the UAV 110 and facingup. At 1022, the UAV 110 can return to the distribution center.

As shown in FIGS. 11A-11C, in some examples, the shipping labelparachute system 104 can comprise a plurality of sizes. As shown, theshipping label parachute system 104 can comprise a small 104 a, medium104 b, and large 104 c shipping label for shipping small, medium, andlarge packages, respectively. In this manner, the size of the shippinglabel parachute system 104 can be adjusted based on the size of therequired parachute system 206, the area required to secure the shippinglabel parachute system 104 to the shipping container 106 (i.e., via thebacking sheet 202), or other factors. In some examples, the weightand/or size constraints for the largest shipping label 104 c, forexample, can be based on the size and/or weight constraints of the UAV110. In this manner, packages that are too heavy or large to bedelivered by UAV 110 can be identified and shipped via alternative modesof transportation.

As shown, each shipping label parachute system 104 a, 104 b, 104 c canbe associated with a related parachute system 206 a, 206 b, 206 c,respectively. In this manner, the size of the parachute system 206 canbe indicated by the size of the exterior of the shipping label parachutesystem 104. This can enable users to readily identify the different sizeand capacity shipping label parachute systems 104. In some examples, thesize of the parachute system 206 may also dictate whether a harness 212is used (FIGS. 11B and 11C) or not (FIG. 11A). As mentioned above, theharness 212 may be desirable to prevent tangling on larger parachutesystems 106 b, 106 c, for example, but may be unnecessary for smallerparachute systems 106 a. Similarly, smaller parachute systems 206 a, forexample, may not require a static line 216, or may use the adhesivestatic system 218, discussed above.

In some examples, each shipping label parachute system 104 can beassociated with one or more matching shipping containers 106. In thismanner, each box, or group of boxes, and the respective shipping labelparachute system 104 have the same weight and/or size requirements. Inthis manner, if the item 904 to be shipped meets the size and weightrequirement for the shipping container 106, it can also be safelydelivered with the related shipping label parachute system 104. In thismanner, the selection of the proper shipping label parachute system104—and the proper parachute system 206—is simplified. In some examples,the shipping label parachute system 104 may be preinstalled on theappropriate shipping containers 106 to avoid mismatches.

In some examples, as shown, the small shipping label 104 a can have asmaller planform than the medium 104 b and large 104 c shipping labels.In this manner, the shipping label parachute system 104, and theirrespective parachute systems 206, can be identified by the size of theshipping label parachute system 104. In other examples, larger parachutesystems 206 can be folded such that all parachute systems 206 fit insideshipping label parachute system 104 of the same dimensions (albeitsomewhat thicker). In some examples, the different sized shipping labelparachute systems 104 may be color-coded, conspicuously labeled, orotherwise identified.

In some examples, the size of the shipping label parachute system 104can be determined based on a predetermined, maximum landing speed forthe shipping container 106. In other words, different items 904 andpacking materials 908 may require different landing speeds to avoiddamage. On the one extreme, a baseball or a towel packed in a shippingcontainer 106, for example, could probably be dropped without aparachute (or with a very small parachute) though the shipping container106 may be damaged. On the other extreme, pottery or wine glasses mayrequire relatively low landing speeds to prevent breakage, regardless ofthe shipping container 106 and packing material 908.

The predetermined landing speed for a shipping container 106 can bedetermined based on, for example, the shock absorbing properties andstrength of the shipping container 106 and packing materials 908,coupled with the strength (or fragility) of the items 904 in theshipping container 106. In some examples, the shipping container 106,packing materials 908, and shipping label parachute system 104 can bematched such that the landing speed of the shipping container 106 islower than the predetermined landing speed for any stocked item 904 thatcan be shipped in that shipping container 106. In other examples, thepredetermined landing speed (or maximum g-force) for each item 904 to beshipped can be determined experimentally to enable an appropriateshipping label parachute system 104, shipping container 106, and packingmaterial 908 “system” to be determined for each item 904.

As shown in FIG. 12, in some examples, more than one shipping labelparachute system 104 can be used. This can be useful for particularlyheavy, large, or awkward shipping container 106. Heavy shippingcontainer 106, for example, may simply exceed the weight limit for thelargest shipping label parachute system 104; and thus, may require morethan one parachute system 206 to provide safe descent. In otherexamples, as shown, the shipping container 106 may be a shipping tube,or similar, that would otherwise dangle or spin precariously from asingle parachute system 206.

In some examples, when multiple shipping label parachute systems 104 areused, the shipping label parachute systems 104 can be placed at apredetermined distance from one another to substantial prevent themultiple parachute systems 206 from interfering with one another. Inother words, the shipping label parachute systems 104 can be placed atsufficient distance from one another to prevent entanglement of therespective parachute cords 210, impingement of one canopy 208 onanother, etc. In other examples, such as when a shipping container 106is only slightly over the weight limit for a single shipping labelparachute system 104, for example, interaction between the two shippinglabel parachute systems 104 may be inconsequential.

While several possible examples are disclosed above, examples of thepresent disclosure are not so limited. For instance, while a system isdescribed primarily for use with UAVs, the system could also be used inconjunction with airplanes, helicopters, and other aerial vehicles. Inaddition, the location and configuration of various features of examplesof the present disclosure such as, for example, the static line hook onthe UAV, the type of harness used on the parachute, or the type andlocation of adhesives on the backing sheet can be varied according to aparticular parachute system, UAV, shipping container, or by weightand/or size constraints placed in the system. Such changes are intendedto be embraced within the scope of this disclosure.

The specific configurations, choice of materials, and the size and shapeof various elements can be varied according to particular designspecifications or constraints requiring a device, system, or methodconstructed according to the principles of this disclosure. Such changesare intended to be embraced within the scope of this disclosure. Thepresently disclosed examples, therefore, are considered in all respectsto be illustrative and not restrictive. The scope of the disclosure isindicated by the appended claims, rather than the foregoing description,and all changes that come within the meaning and range of equivalentsthereof are intended to be embraced therein.
